CAR-TRUCK.

SPECIFICATION forming part of Letters Patent N 0. 700,265, dated May 20, 1902.

Application filed March 19, 1902.

Be it known that I, BENJAMIN W. TUCKER, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Oar-Trucks, of which the following is a specification.

The invention relates to improvements in car-trucks; and it consists in the novel features and combinations of parts hereinafter described, and particularly pointed'outin the claims.

The object of the invention is the production of a car-truck which while possessing desirable structural features in a general sense shall be capable of retaining its squareness or the true right-angular relation ofits side frames and transom and adapted to permit the truck-wheel's to follow the customary irregularities-ofthe trackrails, the transom being capable of a limited torsional action, whereby the wheels at both sides of the truck may maintain their relation to the track-rails at points where, for illustration, the rail at one side of the track may be on a lower plane than the rail at the opposite side thereof.

The invention and satisfactory means for carrying the same into effect will be fully understood from the detailed description hereinafter presented, reference being had to th accompanying drawings, in which I Figure l is a top view of a portion of a truck-frame constructed in accordance with and embodying the invention. Fig. 2' is a of the truck-frame. Fig. 3 isadetached'top view of one of the caps for aiding in securing the end of the transom to the side frame. Fig; 4 is a bottom view of same. Fig. 5isa vertical section of the-truck on the dotted line 5 5 of Fig. 1, and Fig. 6 isa like'section of a portion of same on thed'otted line 66 of Fig.1.

I illustrate in the drawings onlyso much of a car-truck of the known diamondtype' as is' necessary for a full understanding of my invention applied thereto or utilized in connection therewith, the axle-boxes, wheels, bolster bolster-'spr'in gs, and other features incidental to all car-trucks being omitted, since my invention pertains especially to the transoms and features used in connection therewith at the center of the side frames of the of a diamond truck.

Serial No. 98,874. (No model.)

disposed plates 15, upon the facing sides of which are secured the plates 16, the latter strengthening the structure and servingas guiding and rubbing surfaces for the bolster. (Not shown.)

The horizontal flanges of the upper beams 13 extend outwardly toward the ends of the truck, and the horizontal flanges of the lower beams 14 extend inwardly toward the center of thetruck, and the connecting-plates 15 are secured against the faces of the vertical flanges of said beams 13 14, said plates 15 having the laterally-projecting upper. and lower extensions 17, engaging the angle-iron beams 13 14 for a certain distance inward from the side frames of the truck. Intermediate the extensions 17 the plates 15 are cutout on the line of the arc of a circle, as at 18, this curved lineextending from the lower edge of-the up-; 85.;

per beam 13 to the u beam 14. L At each side of the center of the side frames pper edge of the lower of thetruck the lower beam 14 is secured to the plate 15 by means of rivets or bo1ts'19,

and the upper beam 13, plate 15, and plate16 are secured together by means ofv rivets or bolts 20,'while intermediate the upper and lower'beams 13 14 the plate-15 and plate 16 at each side of the center of the side frame 5 are additionally secured together by rivets or bolts 21. The end portions of thehorizontal flanges or members of'the-beams13 are fastened to the arch;bar,10.by meansbf the cast caps 22 and bolts 23, the latter passing vertitoo 1 cally through saidcaps. 22, the horizontal flanges of the beams 13, and the arch-bar 10. The cast caps 22 are recessed on their upper side to pass upwardnpon the lower side ofthe arch-bar 10, and said caps are recessed on their lower side to receive the end portions of the horizontal flanges or members of the upper beams 13, gibs or shoulders 24E being formed on the lower side of the caps 22 to engage the outer edges of the beams 13, while the recesses on the upper side of said caps result in the formation of gibs or shoulders 25 to engage the opposite edges of the arch-bar 10, said shoulders 25 extending at right angles to the shoulders 2%, and thus aiding in holding the truck-frame perfectly square. The caps 22 extend laterally inward beyond the side frames, this portion of the caps covering the upper edge of the upper plate extensions 17 and being fastened to the beams 13 by means of the rivets or bolts 26. The rivets or bolts 26 are also used to take one end of the usual straps 27 for the brakehangers, (not shown,) the other end of said straps being secured by the rivets or bolts 28. The horizontal flanges or members of the lower beams 14 and the lower edges of the plates 15 are seated within recesses 29, formed in a cast base-block 30, which is recessed, as at 31, upon its lower side to fit upon the central level portion of the arch-bar 11.

The tie'bar 12, arch-bar 11, cast base-block 30, and beams 14 are securely fastened together by means of the bolts 32, which pass through apertures in all of said parts. The base-block 30 and beams 14: are also securely fastened together at points at opposite sides of the arclnbar 11 by means of rivets or bolts The shoulders formed at the edges of the recesses 29 in the base-block 30 extend at right angles to the shoulders formed at the edges of the recess 31 in said block, and said shoulders by their engagement with the transoms and arch-bar 11 materially aid in keep ing the truclcframe square.

Upon the base-block 30 is arranged the socket-plate 34:, containing seats for the usual springs (not shown) to receive the ends of the bolster. (Not shown.) The lower side of the socket-plate 31 is recessed to pass over the heads of the bolts 32 33, said heads being thereby enabled to center said plate upon the base-block 30.

The upper and lower angle-bar beams 13 14, connected together at their end portions and secured to the upper and lower arch-bars of the side frames of the truck, result in the production of a truck-frame of great simplicity and durability and one capable of preserving its squareness of form or the true right angularity of the side frames with the transoms, and this is a feature of great importance, since one of the great objections to many truck-frames is their liability to lose their squareness. Another feature of importance due to the present invention is that the upper and lower angle-bar beams while securely connected together at theirendportions are separated along the line of their length between the side frames of the truck, as illustrated more clearly in Fig. 5that is to say, that the vertical webs or flanges of the upper beams 13 are separated from the vertical webs or flanges of the lower beams lit-whereby the space between the upper and lower beams, as shown in Fig. 5, is secured and whereby also the truck-frame when in use may along the transoms be permitted to have a limited twisting or torsional action without disturbing the means whereby the ends of the transoms are secured to the side frames, the result being that the truck-wheels at the opposite sides of the truck may at all times preserve their relation to the track-rails, this function being one I have sought to attain by means of my invention for the purpose of overcoming the objection to many of the rigid truck-frames due to the wheels at the opposite sides of the truck being unable to remain on the track-rails when, for illustration, the truck is passing apoint on the road where one track-rail is on a lower plane than the other track-rail. The truck-frame of the construction herein presented while being a rigid frame is nevertheless capable of a limited torsional action in the transoms,whereby the wheels are permitted to at all times remain upon the rails without disturbing the rigidity of the truck or straining its parts. It is to be observed that the horizontal flanges of the upper angle-iron beams 13 extend outward toward the ends of the truck, while the horizontal flanges of the angle-iron beams 14: extend inward, and this is a feature of importance in that by reason thereof the torsional action hereinbefore referred to is permitted to an advantageous degree. The fact that the horizontal flanges of the beams 13 extend outward and the horizontal flanges of the beams 14: extend inward is also of adv vantage, since by reason thereof the upper beams 13 leave a clear space between the guide-plates 1G for the bolster, and the lower beams 14 are not interfered with by the lower arch-bar 11, but are so disposed that they may be securely fastened to the base-bloclc 30, tie-bar 12, and lower arch-bar 11. The

horizontal flanges of the upper angle-iron beams 13 also afiord supportsvfor the hangers 27 for the brake-rigging.

\Vhile I regard the construction presented as a highly satisfactory embodiment of the invention, I do not wish to limit myself to all of the details of form and construction shown, since it is obvious that some of the details shown may be altered or modified within the scope of my invention. For illustration, the socket-plate 3% contains seats for four coiled springs to receive the bolster; but I do not wish to limit this invention to the employment of the plate 3& having the four seats for the springs, since a greater or smaller number of springs maybe employed, or elliptic in lieu of coiled springs may be employed; nor do I in every instance desire this invention limited to the employment of strictly angle-iron transom-beams 13 14, since a part of my invention would be present if the vertical flanges of the beams 13 1-1 were in part omitted and substantially only the horizontal portions thereof employed,- these horizontal portions being arranged,as shown in the drawings, with the inner edges of the upperbeams about in line with the outer edges of the lower beams, said arrangement omitting the' vertical portions of the beams 13 14, resulting in a desirable form of truck, thoughnotso desirable as when the transom-beams are of angle-irons, with the ends of the'bearns 13 14 connected together and to theside frames with a space left between those portions'of the vertical flanges of said beams disposed intermediate the side frames, said vertical flanges being as nearly as possiblein vertical line, while the horizontal flanges of the beams 13 14 project in opposite directions, as shown. What I claim as my invention, and desire to secure by Letters Patent, is- 1. In a'car-truck, the angle-iron upper and lower transom-beams 13, 14, secured at their ends to the side frames with afree space left intermediate those portions of the vertical flanges of said beams disposedintermediate the side frames, the horizontal flanges of said upper and lower transoms being projected in opposite directions; substantially as set forth.
